NAME: Euphorbia deightonii
FAMILY: Euphorbiaceae (Spurge family)
COMMON NAMES: Deighton's Spurge
LOCAL NAMES: N/A
MORPHOLOGICAL DESCRIPTION: Euphorbia deightonii is a succulent perennial plant that forms a compact rosette of stems. It has thick, fleshy, and cylindrical stems that are often tinged with purple. The stems are covered in small, spine-like structures called tubercles. The leaves are reduced to small scales that appear as tiny spines. The plant produces small, greenish-yellow flowers that are arranged in dense clusters at the center of the rosette.
USEFUL PART(s): The sap or latex of Euphorbia deightonii is the most useful part of the plant.
GENERAL USES:
Traditional Medicine: Like other Euphorbia species, the sap of Euphorbia deightonii has been used in traditional medicine for various purposes. It is believed to have medicinal properties and has been used to treat skin ailments, warts, and other conditions. However, caution should be exercised as the sap can cause skin irritation and should not be ingested.
GEOGRAPHIC DISTRIBUTION: Euphorbia deightonii is native to the arid regions of South Africa, particularly in the Western Cape Province. It is adapted to dry, rocky slopes and sandy soils. The species is endemic to specific areas within its range.
WHY IS IT GREEN? Euphorbia deightonii, like other plants, appears green due to the presence of chlorophyll. Chlorophyll is a pigment that absorbs light energy from the sun, which is then used in the process of photosynthesis to convert carbon dioxide and water into glucose and oxygen. The green color is a result of chlorophyll absorbing blue and red light and reflecting green light.
ENVIRONMENTAL IMPACT: Euphorbia deightonii is adapted to arid environments and is well-suited for xeriscaping and water-wise gardening. As a succulent, it requires minimal watering and can withstand drought conditions. When planted in suitable habitats, it can contribute to the establishment of resilient plant communities in arid regions.
FUN FACT: Euphorbia deightonii is named after R.O. Deighton, a former curator of the Compton Herbarium in Cape Town, South Africa. The plant's spiny appearance and succulent nature are adaptations to the arid conditions in which it grows, helping to conserve water and protect against herbivores.
